Abstract: Underground rocks with vertical aligned fractures can be equivalent to horizontal transversely isotropic (HTI) media. For HTI medium model, the authors studied the inversion method to estimate anisotropic parameter using the seismic amplitude varying with azimuth (AVAZ) of fractured reservoirs. Firstly, in the seismic AVAZ inversion process, the simulated annealing particle swarm optimization algorithm was proposed to invert the anisotropic parameters of fractured reservoirs; then, the validity of seismic AVAZ inversion based on simulated annealing particle swarm optimization algorithm was verified by theoretical model test; finally, the inversion method was applied to the field azimuth seismic data of Longmaxi shale gas reservoir in Sichuan basin. Before inversion, the Fourier series method was used to estimate the fracture orientation and correct the field data to provide more accurate input data. The anisotropic parameters of P and S waves obtained by calculation can be used to evaluate the degree of fracture development. The inversion results show that the fractures on the top of the study area are well developed, which is consistent with the basic geological theory. It verifies the rationality of the inversion method and proves that the inversion results can provide a basis for reservoir fracture identification.

Key words: HTI, fracture, reservoirs, anisotropy, seismic AVAZ, inversion, Sishuan basin, shale gas
